{Embodiment}
Hereinafter, the binding band tightening training apparatus according to the embodiment will be described. The binding band tightening training device is a device for training a binding band tightening cut operation included in the manufacturing process of the wire harness. More specifically, the tightening cut operation refers to an operation of tightening and cutting the tip of a binding band wound around a linear body such as an electric wire. At this time, the operator performs a tightening cut operation using a band tightening cut tool. Here, if the skill level relating to the handling of the band tightening cut tool by the operator is high, the production speed and the quality of the product are improved accordingly. Therefore, it is required to improve the skill level of the worker to a certain level at an early stage. The apparatus for binding band tightening training according to the present embodiment is for increasing the skill level relating to the handling of the band tightening cutting tool.

Specifically, the binding band tightening training apparatus includes a linear body and a support member that supports the linear body, a training binding band, and a training band tightening tool. Here, a description will be given assuming that a rotating plate is used as a support member for supporting the linear body.

First, the rotating diagram board 20 will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view showing a rotating diagram board 20 in the binding band tightening training apparatus 10. FIG. 2 is a side view showing the rotating diagram board 20 in the binding band tightening training apparatus 10. Specifically, the rotating drawing board 20 includes a drawing board main body 22, a linear body support portion 24, and a rotation mechanism 26.

The figure body 22 is formed in a flat plate shape. Here, the figure main body 22 is formed in a disk shape. However, the shape of the figure board main body 22 is not limited to the above-described one, and may be formed in a square plate shape, for example.

The linear body support 24 is provided on the drawing board main body 22. The linear body W can support the linear body W to which the binding band 30 for training is attached. A plurality of linear body support portions 24 are provided. The plurality of linear body support portions 24 are arranged so that the linear body W can extend from one position in at least three directions. The plurality of linear body support portions 24 can be arranged in steps of 15 degrees around one central point of the drawing board main body 22.

Here, as the linear body support portion 24, a jig called a U jig 25a having a U-shaped tip is employed. The U jig 25a is fixed to the drawing board main body 22 with, for example, screws. Therefore, here, the board body 22 is formed with a screw hole 23a into which a screw for fixing the U jig 25a can be screwed. Screw holes 23a are concentrically provided in the drawing board main body 22 in increments of 15 degrees. Of these, the U jig 25a is disposed in the screw hole 23a at a position shifted by 45 degrees. A screw hole 23b is also provided at the center of the concentric circle. Using the screw hole 23b, a four crotch jig 25b such as a combination of two U jigs 25a is installed.

The rotation mechanism 26 is rotatable around an axis along a direction (here, a direction orthogonal) that intersects the main surface of the drawing board main body 22 with respect to the main surface of the drawing board main body 22. As the rotation mechanism 26, here, a shaft portion 27 provided in a non-rotatable manner on the drawing board main body 22 and a support base 28 that rotatably supports the shaft portion 27 are provided. The rotation mechanism 26 preferably does not rotate the drawing board main body 22 during the band tightening operation. For example, the rotation mechanism 26 is configured to be capable of screwing and fixing the shaft portion 27 with respect to the support base 28, and the drawing board main body 22 is screwed and unrotatable, and the screw tightening is released and rotatable. It is conceivable that the state can be changed between.

For example, a linear body W is disposed on the rotary diagram board 20 as shown in FIG. FIG. 3 is a plan view showing an example of the arrangement of the linear bodies W on the rotary diagram board 20.

In the example shown in FIG. 3, the linear body W is arranged in such a manner that the linear body W extends in eight directions from the center of the drawing board main body 22. Hereinafter, a line extending in eight directions may be referred to as a branch line. Here, two of the branch lines that extend to the left and right are formed thicker than the others. This is because the trunk line is usually thicker than the branch line in the wire harness. However, the extending direction and thickness of each branch line can be set as appropriate. In addition, the linear body W is good to be united integrally with the adhesive tape etc. Further, here, since it is for training, the portion of the linear body W that extends outward from the U jig 25a can be omitted.

In the example shown in FIG. 3, the training binding bands 30 are wound around the eight branch lines at two different points in the longitudinal direction. Therefore, when viewed as a whole, 16 training tie bands 30 are wound.

Next, the training binding band 30 will be described with reference to FIGS. 4 to 6. FIG. 4 is a plan view showing the training binding band 30 in the binding band tightening training apparatus 10. FIG. 5 is a cross-sectional view taken along line VV in FIG. FIG. 6 is an explanatory view showing a state in which the locking of the band part 32 and the band locking part 36 is released. Specifically, the training binding band 30 includes a band part 32, a band locking part 36, and a locking release part 42.

The band part 32 is a member formed in a long band shape. The band portion 32 is formed with an uneven portion 33 into which the protrusion 40 of the band locking portion 36 is fitted. The concavo-convex portion 33 is formed in a shape in which convex portions 35 and concave portions 34 are alternately continued along the extending direction of the band portion 32. In the example shown in FIG. 5, the uneven portion 33 is formed on the main surface (inward surface) that faces inward when the band portion 32 is wound around the linear body W. But the uneven | corrugated | grooved part 33 may be formed in the outward surface facing the inward surface among the band parts 32, and may be formed in the side surface.

The band locking portion 36 is formed so that the tip of the band portion 32 can be inserted. Further, the band locking portion 36 is formed so as to be able to lock the inserted band portion 32. The band locking portion 36 is provided at the base end of the band portion 32. Here, the band locking portion 36 includes a band insertion portion 37 and a protrusion 40.

The band insertion portion 37 includes an insertion main body portion 38 formed in a rectangular parallelepiped shape and a through hole 39 formed in the insertion main body portion 38. The through hole 39 is formed so as to penetrate the pair of main surfaces of the insertion main body portion 38 in a manner in which the band portion 32 can be inserted.

The protrusion 40 is formed so as to protrude from the inner peripheral surface of the through hole 39 toward the inside of the through hole 39. The protrusion 40 is formed in a shape that fits into the concave portion 34 of the concave and convex portion 33. More specifically, the surface 35a facing the front end side of the convex portion 35 and the surface 40a facing the rear end side of the protrusion 40 are formed in an inclined surface shape. As a result, when the band portion 32 tries to move in a direction that is deeply inserted into the through-hole 39, the uneven portion 33 and the projection 40 slide on the

inclined surfaces

35a and 40a, and at least one of them is elastically deformed to move. ing. Further, the surface 35b facing the rear end side of the convex portion 35 and the surface 40b facing the tip end side of the protrusion 40 are formed in a vertical plane shape. As a result, when the band portion 32 tries to move in the direction of coming out of the through hole 39, the vertical surface 35 b of the convex portion 35 and the vertical surface 40 b of the protrusion 40 are in surface contact with each other and spread in a direction perpendicular to the insertion direction. It is considered impossible to move.

The locking release part 42 can release the locking between the band part 32 and the band locking part 36. Here, the locking release part 42 is formed so that the protrusion 40 can be elastically deformed via an operation part 43 extending from a part of the protrusion 40. More specifically, the operation portion 43 protrudes downward from the lower surface of the protrusion 40. The front end side portion of the operation unit 43 is arranged at a distance from the portion of the training binding band 30 that is located around the operation unit 43. Therefore, an operation space 44 is provided around the operation unit 43 so that the operation unit 43 can be moved. Then, as shown in FIG. 6, the protrusion 40 is moved to the band insertion portion 37 by moving the distal end side portion of the operation portion 43 in a direction approaching the proximal end portion of the band portion 32 (direction indicated by the arrow in FIG. 6). And elastically deformed in a direction away from the recess 34 around the connecting portion. Thereby, since the lock | rock with the band part 32 and the band latching | locking part 36 is cancelled | released, the band part 32 can be extracted from the through-hole 39. FIG. That is, the band part 32 in the locked state (the state shown by the phantom line in FIG. 5) can be returned to the state before the locked state (the state shown by the solid line in FIG. 5).

In addition, it is preferable that the binding band 30 for training is wound around the linear body W in a different posture. More specifically, the extending direction of the band portion 32 from the band locking portion 36 intersects with the main surface of the figure board main body 22, the direction orthogonal to the main face of the figure board main body 22, and these. It is preferable to set various directions. Thereby, the handleability of the band tightening tool for training with respect to the band part 32 extended in various directions can be trained.

Next, the training band tightening tool 50 will be described with reference to FIGS. FIG. 7 is an explanatory diagram showing the configuration of the training band tightening tool 50 in the binding band tightening training apparatus 10. FIG. 8 is an explanatory diagram showing the configuration of the training band tightening tool 50 in the binding band tightening training apparatus 10. 9 to 14 are explanatory views in which a part of the training band tightening tool 50 is enlarged. 9 and 10 are enlarged views of the vicinity of the distal end side of the training band tightening tool 50, and FIGS. 11 to 14 are enlarged views of the vicinity of the intermediate portion of the training band tightening tool 50. FIG.

The training band tightening tool 50 is a tool used by an operator when tightening the training binding band 30. The training band tightening tool 50 does not have a function of cutting the band portion 32. For this reason, the band part 32 tightened to a state having a predetermined tension by the training band tightening tool 50 is maintained in a state of extending from the band locking part 36. Specifically, the training band tightening tool 50 includes a holding portion 54, a handle 60, a trigger 62, a tightening mechanism 64, and a locking mechanism 74.

The holding portion 54 is provided at the distal end of the long casing 52 in the training band tightening tool 50. The holding part 54 holds the tip of the band part 32 protruding from the band locking part 36. Specifically, the holding unit 54 includes a holding claw 55, a receiving member 56, and a claw posture regulating member 57.

The holding claw 55 is provided at the tip of a claw link member 72 described later of the tightening mechanism 64, and reciprocates in the front-rear direction together with the claw link member 72. The holding claw 55 is disposed away from the receiving member 56. The band portion 32 inserted between the holding claw 55 and the receiving member 56 can be sandwiched between the receiving member 56. The holding claw 55 is rotatably supported so that the direction of the tip can be changed. At this time, the holding claw 55 is rotated so that the tip portion extends in parallel with the receiving member 56 (see FIG. 9) and the second posture in which the tip portion faces the receiving member 56 side (FIG. 10). The position can be changed. In the first posture, the band portion 32 can be easily inserted between the holding claw 55 and the receiving member 56. Further, in the second posture, the band portion 32 can be held between the holding claw 55 and the receiving member 56. For example, the holding claw 55 is urged to take the second posture by an urging member (not shown). Further, the posture of the holding claw 55 is restricted to the first posture by the claw posture restricting member 57 when the trigger 62 is in the initial position. When the trigger 62 is pulled from this state, the holding claw 55 moves rearward and moves away from the claw posture regulating member 57. Accordingly, the holding claw 55 can take the second posture by receiving the urging force of the urging member 80.

The receiving member 56 is a member that holds the band portion 32 together with the holding claw 55. For example, the receiving member 56 is formed in an L shape so as to bend in the middle and extend in the width direction while extending upward from one width direction of the long casing 52. Accordingly, the band portion 32 can be set between the holding claw 55 and the receiving member 56 from the side while the band portion 32 can be clamped together with the holding claw 55.

The claw posture regulating member 57 is provided at the tip of the long casing 52 between the holding claw 55 and the receiving member 56. The claw posture regulating member 57 is provided only in a part of the section along the movement path of the holding claw 55, for example. As a result, when the holding claw 55 moves to the rear end side of the long casing 52, the holding claw 55 can move away from the claw posture regulating member 57 and change the posture from the first posture to the second posture. It has become. Further, when the holding claw 55 moves to the front end side of the long casing 52, the holding claw 55 rotates by the rear end portion of the claw posture regulating member 57 coming into contact with the front end side of the holding claw 55. The posture can be changed from the two postures to the first posture.

The handle 60 is a part held by the operator. The handle 60 extends from the rear end side of the long casing 52 in a direction intersecting the long direction of the long casing 52. Thereby, the training band tightening tool 50 has a pistol-like shape as a whole. The handle 60 is provided integrally with the long casing 52, for example.

Trigger 62 is a portion where exercise is input by an operator. The trigger 62 is disposed so as to be separated from the handle 60, and can be moved toward and away from the handle 60.

The tightening mechanism 64 is a mechanism that converts the motion input to the trigger 62 into a motion for tightening the tip of the band portion 32 held by the holding portion 54. The tightening mechanism 64 includes a trigger link member 66 and a claw link member 72.

The trigger link member 66 includes a first link member 68 and a second link member 70 supported by the trigger 62, respectively.

The first link member 68 has one end side 68 a supported by the trigger 62 and the other end side 68 b supported by a cam member 76 described later of the locking mechanism 74. Here, the one end side 68 a is fixed to the trigger 62 so as to be movable with the trigger 62 and not rotatable with respect to the trigger 62. Here, the intermediate portion 68c is also supported by the trigger 62 so as to be movable together with the trigger 62. The other end side 68b is supported rotatably with respect to the cam member 76. For example, the pin member P inserted through a through hole formed on the other end side 68 b is supported by a groove 78 described later of the cam member 76.

Here, a link member (not shown) is provided outside the first link member 68. One end side of the link member is fixed to the trigger 62 so as not to rotate at the same position as the one end side of the first link member 68, and the other end side can be rotated to the long casing 52 on the extension line of the pin member P in the initial state. Is pivotally supported.

The second link member 70 has one end side 70 a supported by the trigger 62 and the other end side 70 b supported by the claw link member 72. Here, the one end side 70 a is pivotally supported by a portion where the intermediate portion 68 c of the first link member 68 is supported so as to be movable together with the trigger 62 and relatively rotatable with the trigger 62 and the first link member 68. The other end side 68 b is fixed to the claw link member 72 so as to be movable together with the claw link member 72. The second link member 70 is urged toward the front in the longitudinal direction of the long casing 52 by an urging member (not shown). As a result, the trigger 62 is biased in a direction away from the handle 60.

The claw link member 72 is formed in a long shape along the long direction of the long casing 52. The holding claw 55 is provided at the tip of the claw link member 72. The second link member 70 is connected to the rear end of the claw link member 72.

The locking mechanism 74 is a mechanism for preventing further tightening when the tip of the band portion 32 is tightened to a state having a predetermined tension. The locking mechanism 74 includes a cam member 76, a biasing member 80, a pinion 82, and a rack 84.

The cam member 76 is rotatably supported by the long casing 52 by the shaft portion 77. The cam member 76 is formed with a groove 78 for supporting the pin member P on the distal end side. Further, a biasing member 80 is connected to the rear end side.

The groove 78 cannot move when the pin member P cannot move rearward in the longitudinal direction with respect to the cam member 76, and cannot move when a force less than a predetermined tension is applied forward in the longitudinal direction. It is formed in a movable shape when a force greater than the tension is applied. Here, the inner surface 78a on the rear end side of the groove 78 is formed in a vertical plane extending in a direction orthogonal to the longitudinal direction in the initial state. Further, the inner surface 78b on the distal end side of the groove 78 is formed in an inclined surface shape that intersects the longitudinal direction and the direction in which the vertical surface extends in the initial state.

The urging member 80 urges the cam member 76 toward the rear of the long casing 52. The urging force of the urging member 80 defines the tension. The urging member 80 is configured by, for example, a coil spring.

It is preferable that the biasing member 80 can adjust the biasing force. Here, the urging force of the urging member 80 can be adjusted by the adjusting screw mechanism 86. Specifically, the adjustment screw mechanism 86 includes an adjustment dial 87 provided outside the casing, and an adjustment screw 88 having one end connected to the adjustment dial 87 and the other end connected to the other end of the biasing member 80. The By turning the adjustment dial 87, the position of the tip of the adjustment screw 88 can be changed. Thereby, the spring length of the coil spring can be changed, and the urging force of the urging member 80 can be adjusted.

The pinion 82 is formed in an L shape. A tooth portion 83 is provided at the tip of the other end side 82b while the one end side 82a of the pinion 82 is in contact with the rear end side of the cam member 76. Further, the pinion 82 is rotatably supported by the long casing 52 at its intermediate portion 82c. The pinion 82 is urged to rotate by an urging member (not shown) so that the one end side 82 a approaches the cam member 76. Therefore, it can be said that the cam member 76 regulates the rotation of the pinion 82. The tooth portion 83 is provided apart from the rack 84 in the initial state. When the pinion 82 is rotated by the rotation of the cam member 76, the tooth portion 83 is engaged with the rack 84.

The rack 84 is continuously formed on the upper surface of the claw link member 72 along the longitudinal direction. The rack 84 is formed in a region located below the tooth portion 83 when the claw link member 72 moves.

Hereinafter, the band tightening training using the binding band tightening training apparatus 10 will be described.

First, as shown in FIG. 3, a rotating diagram board 20 on which a linear body W is arranged is prepared. At this time, the binding band 30 for training is wound around the linear body W. It is preferable that the binding band 30 for training is wound around the linear body W so as not to rotate around the linear body W. Thereby, the tightening operation | work of the binding band 30 for training can be performed, with the band part 32 maintaining the state extended in various directions along the radial direction of the linear body W. FIG.

Next, the operator uses the training band tightening tool 50 to sequentially tighten the training band 30.

Specifically, first, the tip of the band portion 32 extending from the band locking portion 36 is passed between the holding claw 55 and the receiving member 56 in the first posture by the claw posture regulating member 57. As described above, the band portion 32 can be passed between the sides. Next, the operator pulls the trigger 62 and tightens the band portion 32. More specifically, when the operator pulls the trigger 62, a portion of the trigger link member 66 fixed to the trigger 62 moves backward. Thereby, the claw link member 72 linked to the trigger link member 66 also moves rearward. When the claw link member 72 moves slightly rearward, the contact state between the holding claw 55 and the claw posture regulating member 57 is released. For this reason, the state in which the posture of the holding claw 55 is restricted is released, the holding claw 55 is changed to the second posture, and the band portion 32 is sandwiched between the receiving member 56. In this state, when the trigger 62 continues to be pulled, the holding claw 55 moves backward, so that the band portion 32 also moves backward, and the band portion 32 is tightened. At the time of tightening, even if the trigger 62 shown in FIG. 12 is fully pulled from the initial state shown in FIG. 11, if the tension does not exceed a predetermined value, the trigger 62 is returned to the original state and the trigger is triggered again. The operation of pulling 62 is repeated.

On the other hand, as shown in FIG. 13, between the state shown in FIG. 11 and the state shown in FIG. 12, when the tension becomes a predetermined value or more, the pin member P jumps out of the groove 78 and the cam member 76 rotates. As shown in FIG. 14, the rack 84 and the teeth 83 are engaged with each other and locked in that state.

More specifically, in the initial state, the cam member 76 is going to rotate clockwise around the axis by the urging force of the urging member 80. At this time, the rotation of the pin member P is suppressed by fitting into the groove 78. When the trigger 62 is pulled, the one end side 68 a of the first link member 68 moves rearward together with the trigger 62. At this time, in a state where the tension is weak, the intermediate portion 68 c also moves backward together with the trigger 62. At this time, the other end side 68 b of the first link member 68 also moves backward together with the trigger 62. However, since the movement of the other end side 68b of the first link member 68 is prevented by the vertical surface 78a of the groove 78, the first link member 68 is moved around the central axis of the pin member P together with the pin member P on the other end side 68b. Rotate. That is, the pin member P idles with respect to the cam member 76. Thereby, the pin member P does not come out of the groove 78 and the tightening is continued.

On the other hand, if the tension increases when the trigger 62 is pulled, resistance is generated when the claw link member 72 moves rearward. This resistance hinders the backward movement of the intermediate portion 68c of the first link member 68, and the first link member 68 rotates counterclockwise around the axis of the intermediate portion 68c. Then, the pin member P provided on the other end side 68 b of the first link member 68 pushes the surface on the tip end side of the groove 78 so as to escape from the groove 78. When the tension exceeds a predetermined value, that is, when the moment around the axis due to the pushing force becomes equal to or greater than the moment around the axis due to the biasing force of the biasing member 80, the cam member 76 rotates counterclockwise. As a result, the pinion 82 also rotates, so that the tooth portion 83 meshes with and engages with the rack 84.

At this time, it is preferable that the operator can feel the locking with a sensory organ such as touch or hearing. For example, when the handle 60 becomes heavier with the locking, it is possible to feel the locking by touch. In addition, when locking is performed, a fitting sound is generated between the tooth portion 83 and the rack 84, so that locking can be felt by hearing.

With the locking mechanism 74 locked, the band tightening operation related to one training binding band 30 is completed. After that, by repeating this as many times as the number of binding bands 30 for training, the first band tightening training using the rotating drawing board 20 is completed. Thereafter, by releasing the locked state of the band portion 32 by the locking release portion 42, the training binding band 30 can return to the state before tightening. Thereby, the band tightening training can be repeatedly performed using the binding band tightening training apparatus 10.

Here, as shown in FIG. 15, by rotating the figure main body 22 of the rotary figure 20, the operator is trained around the linear body W extending in a different direction while staying at one position. The tightening work of the binding band 30 can be performed.

It should be noted that a normal band tightening cutting tool used for manufacturing a wire harness often does not require a special operation when shifting from a state where the band is sufficiently tightened and locked to a cutting operation. For example, in the tool described in Japanese Patent Application Laid-Open No. 2014-148354, as in the present invention, when the pin member comes out of the cam member, the pinion meshes with the rack and is locked. At this time, a cutting mechanism is connected to the pin member, and the cutting mechanism is configured to cut the band portion as the pin member escapes from the cam member. For this reason, a series of operations from the tightening operation to the cutting operation can be trained by using the binding band tightening training apparatus of the present invention.

According to the binding band tightening training apparatus 10 configured as described above, the training band tightening tool 50 continues to extend the band portion 32 tightened to a state having a predetermined tension from the band locking portion 36. In order to maintain the state, the tightened band portion 32 is not cut. At this time, since the binding band 30 for training is provided with the lock release portion 42, the tightened band portion 32 can be easily returned to the original state. From these, it becomes easy to repeatedly use one training binding band 30 for training related to the handling of the training band tightening tool 50 similar to the band tightening cutting tool. Therefore, this binding band tightening training apparatus 10 is suitable for training of band tightening cut work.

Also, by using the rotating drawing board 20, the drawing board main body 22 rotates, so that the extending direction of the linear bodies W that can be trained while the operator is still in one working position is increased.

Also, when the training binding band 30 is attached near the branch portion, the work area becomes relatively narrow due to the presence of other branch lines. Even in this case, since the branch line extends from one branch portion in at least three directions, the band tightening work of the training binding band 30 attached in the vicinity of the branch portion can be trained.

Further, since the linear body support portions 24 can be arranged in 15 degree increments with respect to the drawing board main body 22, the arrangement forms of the linear bodies W that can be trained become more diverse.

{Modification}
In the embodiment, it has been described that the rotating drawing board 20 is used, but this is not essential. Instead of the rotating drawing board 20, a drawing board (a drawing board that does not include the rotating mechanism 26) that is normally used for manufacturing a wire harness may be employed. In addition, about the said rotation chart board 20 provided with the rotation mechanism 26, it can use not only for training but in an actual assembly line.

Further, even when the rotary diagram board 20 is used, the rotary diagram board 20 does not have to be capable of arranging three or more linear body support portions 24. That is, the rotary diagram board 20 may support only one linear body W extending in one direction.

In the embodiment, the training binding band 30 has been described as including the band portion 32 and the band locking portion 36, but the binding band may further include a vehicle fixing portion. The vehicle fixing portion includes, for example, a column portion protruding from the upper surface of the band locking portion 36 and a wing portion provided at the tip of the column portion, and is formed so as to be insertable and lockable in an attachment hole formed in an attachment target. The When using a training binding band including such a vehicle fixing portion, a jig capable of fixing the vehicle fixing portion may be provided on the rotary drawing plate 20. Thereby, the binding band for training is more reliably positioned with respect to the linear body W. Further, even when the band portion 32 is temporarily locked with the linear body W before the tightening operation, the training binding band does not rotate around the linear body W.

In the embodiment, the training band tightening tool 50 is described as not including the cutting mechanism itself, but this is not essential. For example, a training band tightening tool can be obtained by omitting only the blade member from a cutting mechanism in an existing band tightening cutting tool such as the tool described in JP-A-2014-148354.

In the embodiment, the training band tightening tool 50 has been described as including a link mechanism that converts the reciprocating movement of the trigger 62 into the reciprocating movement of the holding claw 55 directly, but this is not essential. For example, the trigger 62 may function as a switch, and the holding claw 55 may be reciprocated by air or electricity. As such a band tightening tool for training, a configuration relating to a tightening operation of a known air or electric type band tightening cut tool can be employed.

In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
